Title
(EN) DETERMINATION OF PHYSICAL DOWNLINK CONTROL CHANNEL (PDCCH) ASSIGNMENT IN POWER SAVING MODE
(FR) DÉTERMINATION D'ATTRIBUTION DE CANAL DE COMMANDE DE LIAISON DESCENDANTE PHYSIQUE (PDCCH) DANS UN MODE À ÉCONOMIES D'ÉNERGIE
Abstract
(EN)
A user equipment(UE), a base station, and a method for receiving physical downlink control channels(PDCCHs). The UE includes a receiver and a processor and is configured to receive a configuration for one or more search space sets(SSS) for reception of PDCCHs. The UE is configured to determine a PDCCH reception occasion according to the configuration of the one or more search space sets. The PDCCH reception occasion is prior to an ON duration of a discontinuous reception(DRX) cycle after a second DRX cycle. The UE is also configured to determine an indication to either receive the PDCCHs when the PDCCH reception occasion does not overlap with an extended Active Time of the second DRX cycle or to suspend reception of the PDCCHs when the PDCCH reception occasion overlaps with the extended Active Time of the second DRX cycle.

La présente invention concerne un équipement utilisateur (UE), une station de base et un procédé pour recevoir des canaux de commande de liaison descendante physique (PDCCH). L'UE comprend un récepteur et un processeur et est configuré pour recevoir une configuration pour un ou plusieurs ensembles d'espaces de recherche (SSS) pour la réception de PDCCH. L'UE est configuré pour déterminer une occasion de réception de PDCCH selon la configuration du ou des ensembles d'espaces de recherche. L'occasion de réception de PDCCH est antérieure à une durée de marche d'un cycle de réception discontinue (DRX) après un second cycle de DRX. L'UE est également configuré pour déterminer une indication pour recevoir les PDCCH lorsque l'occasion de réception de PDCCH ne chevauche pas un temps actif étendu du second cycle de DRX ou pour suspendre la réception des PDCCH lorsque l'occasion de réception de PDCCH chevauche le temps actif étendu du second cycle de DRX.
